Abstract
Cross-sections have been computed for the excitation of ortho- and para-NH3 by both ortho- and para-H2, using the quantum-mechanical close-coupling method. The dependences of the cross-sections on the rotational state of the H2 molecule and on different determinations of the dispersion energy of interaction are investigated. The results are discussed in the context of recent crossed-beam measurements of NH3–H2 scattering.Keywords
